Let the present age of man be x years & the present age of his son be y years. Five years ago, Man's age = x- 5 yrs & son's age = y-5 yrs According to Q, (x-5) = 7(y-5) ⇒ x-5 = 7y - 35 ⇒ x = 7y - 30 .....(1) Ratio of their ages after 3 yrs is given as 3:1 ⇒ (x+5)/(y+5) = 3/1 ⇒(x+5) = 3(y+5) ⇒ x+5 = 3y + 15 ⇒ x = 3y + 10 ....(2) Equating 1 & 2 we have 7y - 30 = 3y + 10 ⇒ 4y = 40 ⇒ y = 10 therefore, x = 3(10) + 10 = 40 Hence, present age of man is 40 yrs & present age of his son is 10 yrs.
